Description

Benzoyl Chloride, 2,4,5-Trimethyl- (7Ci,9Ci) CAS NO 34824-32-3 is a specialized aromatic acid chloride derivative, serving as a high-value chemical intermediate for advanced organic synthesis. Its core value lies in its reactivity as an acylating agent, enabling the efficient introduction of the 2,4,5-trimethylbenzoyl moiety into target molecules. This compound is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries who require precise and reliable building blocks for creating complex active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly in developing proprietary drug candidates.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators where the substituted benzoyl group imparts specific biological activity.
• Polymer Chemistry: Acts as a monomer or modifying agent in the synthesis of specialty polymers, including polyesters and polyamides, for high-performance materials.
• Dyestuff and Pigment Manufacturing: Serves as a precursor for synthesizing complex organic dyes and pigments with enhanced color fastness and stability.
• Organic Synthesis Reagent: A versatile acylating agent in academic and industrial laboratories for peptide coupling, esterification, and amide bond formation reactions.
• Liquid Crystal and OLED Material Production: Utilized in creating advanced organic electronic materials due to its ability to form rigid, aromatic core structures.

Quality Control

Every batch of our 2,4,5-Trimethylbenzoyl Chloride is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including GC, HPLC, and NMR, is performed to verify identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
